Combating Short-Lived Climate Pollutants (SLCPs)
You encounter them every day: soot from auto exhaust and burning wood (black carbon), gases that make refrigerators and air conditioners cool (hydrofluorocarbons), natural gas that makes your stove work (methane), and ground-level ozone formed by sunlight and fossil-fuel emissions. Short-live climate pollutants are all around us. And controlling them holds great potential in the fight against climate change.
Short-lived climate pollutants (SLCPs) are so named because they last a relatively short time in the atmosphere, from a few days to a few decades. In contrast, carbon dioxide (CO2) can last centuries. Yet they’re a major contributor to climate change, degrade air quality, and have grave impacts on food security and the health of the world’s most vulnerable populations.
According to the Intergovernmental Panel on Climate Change, SLCPs are responsible for more than 30 percent of global warming (more recent studies estimate their contribute to be as high as 45 percent).
Effective control of SLCPs could create significant progress in the near-term fight against climate change, buying time to implement long-term solutions. It could also mean better air quality, a reduction in premature deaths from respiratory and heart disease, and improved crop yields.

Why we’re working for climate justice in Latin America
“The world has many problems, but to me none seem as ubiquitous or as dangerous as climate change,” says AIDA attorney Florencia Ortúzar. “It really is the great challenge of our generation.” At AIDA we understand the magnitude of the problem. That’s why we incorporate climate justice as a key concept in all our lines of work. It’s why we advocate for sustainable development that respects the environment and the rights of vulnerable communities and, at the same time, why we work to stop climate-aggravating activities. “What motivates me to fight climate change is my awareness of the huge problem we’re facing, and my steadfast determination—I know we can’t give up,” Florencia says. She shares that motivation with AIDA’s entire team of attorneys, scientists, communicators, fundraisers and administrators. When she was a child, Florencia received a very special gift from her father: a badge that said “world saver.” That very day, on a beach in her native Chile, Florencia hooked the badge to her clothes and began picking up trash, cleaning the beach. That small gift jumpstarted her life’s mission. Florencia went on to study law, with the goal of working for the protection of forests, rivers, animals, and all the elements of the natural world. “Luck was with me when I found AIDA, the organization that has trained me and has enabled me to make my contribution to a better world,” she says. Florencia is part of AIDA’s Climate Change program. Our objective is to help Latin America—one of the regions most vulnerable to the climate crisis—be a leader in the type of changes required on a global level to avoid catastrophe. In partnership with allied organizations and hand-in-hand with communities, we work to stop the blind advance of fracking and large dams, mega-projects which imply significant emissions of methane, a greenhouse gas 34 times more powerful than carbon dioxide. We also work to raise awareness and educate public policy makers on the importance of controlling short-lived climate pollutants. We seek to protect terrestrial and marine ecosystems that capture carbon emissions—such as coral reefs, mangroves, wetlands and páramos—which, in turn, helps to mitigate climate change. We monitor international climate negotiations, advocate for Latin American nations to have the necessary economic resources to deal with climate change, and work to ensure that climate finance respects human rights. “Although many of the effects of climate change are inevitable, and may already be occurring, the efforts we make to stop the problem and to adapt to it will help future generations, who had nothing to do with causing the problem,” Florencia explains. She shares her message wherever she goes, encouraging others to join the fight. “I refuse to be part of the last generation to enjoy the natural wonders of our planet.”

The IPCC climate report: science has spoken and we must act now
The international scientific community has spoken: the only thing that can save us from a climate catastrophe is a radical and immediate change. The next 11 years are the most important in the history of the planet, in terms of climate change. Our response to their message will determine our future. In its most recent analysis, the Intergovernmental Panel on Climate Change (IPCC) of the United Nations establishes the impacts that could occur if the planet’s average temperature increases by more than 2°C, and compares those with what would happen if we stop warming, or at least keep it below 1.5°C. The 2016 Paris Agreement, an international accord to curb climate change, aims to keep warming well below 2°C with respect to pre-industrial levels, and to continue global efforts to limit it to 1.5°C. The impacts of global warming The IPCC experts’ conclusions are piercing. Those extra 0.5°C would be lethal for millions of people and their ways of life. If the Earth warms 2°C or more, we would experience: more frequent and intense heat waves, droughts and floods; sea level rise of an extra 10 centimeters, implying coastal flooding and filtration of salt water into agricultural areas and freshwater sources—a matter of life and death for roughly 10 million people; double the risk of habitat loss for plants and vertebrates, and triple the risk for insects, considering more than 100 thousand species which were studied; the disappearance of more than 99% of coral reefs, while 10 to 30 percent of what remains could be saved if we were to stabilize the planet’s temperature below 1.5°C; an increase in the range of mosquitoes that transmit diseases such as malaria and dengue; and the devastation of crops and livestock, severely affecting global food security. So, how are we doing now? Not so well. The planet has already warmed 1°C since preindustrial times, and in 2017 the emissions responsible for warming increased again. The commitments nations made to comply with the Paris Agreement are insufficient. Settling on that level of ambition would take us to 3°C warming by 2030, a reality with unimaginable consequences. Changing our climate destiny Let’s talk about solutions. Ensuring that the planet’s warming doesn’t exceed 1.5°C is possible, but it will require unprecedented action. Emissions must lower by 45 percent between 2010 and 2030, and we must achieve carbon neutrality by 2050. That means not emitting more than what the world’s forests and natural carbon sinks can absorb. This will require that: the most polluting industries, particularly those producing fossil fuels, implement radical changes; renewable energy is the norm by 2050, accounting for between 70 and 85 percent of total energy production; coal-fired power plants disappear; transportation runs with clean, renewable electricity; and we expand, maintain, and care for forests and other natural carbon sinks, which are responsible for removing emissions from the atmosphere. The IPCC report also recognizes a monumental opportunity: the mitigation of short-lived climate pollutants (SLCPs)—including black carbon or soot, methane, hydrofluorocarbons and tropospheric ozone. More climatically intense than carbon dioxide, SLCPs are responsible for half of global warming. Because of their short duration in the atmosphere, they could play a key role in reducing warming in the short term. In addition, the reduction of SLCPs brings important benefits for human well-being, including the reduction of pollution that affects public health and better yield of crops. But few countries have included the reduction of short-lived climate pollutants in their national commitments on climate change. At AIDA we’re working so that Latin American nations advance in the control of these emissions. As the region with the greatest potential for renewable energies, Latin America has the opportunity to be an example for the rest of the planet. The threats facing the region are great and avoiding them is well worth the effort. Climate change threatens to shake us from our very roots—melting Andean glaciers, increasing droughts and floods, diminishing freshwater supplies, driving species to extinction, increasing wildfires, favoring the spread of invasive species, losing corals and marine biodiversity, affecting food security, and wreaking havoc on people’s health and livelihoods. The outlook is clear: maintaining global warming below 1.5°C is not an easy task, but science holds it’s possible. We have the scientific knowledge, and the technological and financial capacity to achieve this goal. The responsibility now lies with governments, decision-makers and the private sector—together they must drive unprecedented changes. We must remember that implementing these changes is not just possible, it’s desirable. A world with fewer emissions is a cleaner and a fairer world for us and for future generations. What’s not to like?

We all deserve to breathe clean air
I was born and raised in Bogota, Colombia’s bustling capital city. When I was a child, I grew accustomed to the chaos of the streets—thousands of cars and buses spewing black smoke into the air, the endless honking of horns. It was normal to see massive smokestacks and smell bad odors. I thought all cities were that way, and that nature and clean air only existed in places far from home. I was used to having health problems: headaches, rashes, eye and throat irritation, coughs and hay fever. I never questioned why my sisters and I were constantly fighting these “environmental allergies.” Pollution even prevented me from enjoying the outdoors. I couldn’t easily walk or ride my bike, for example, because my lungs struggled from the soot emitted by passing trucks and buses. There were days I had to leave my house wearing a mask, and times when we were forbidden from playing outside due to the pollution. Air pollution: a silent killer As an adult, I realized that environmental allergies are not the norm. Often, they are caused by constantly breathing in black carbon, ozone, sulfur dioxide and other pollutants that cars, buses and factories emit into the atmosphere each day. I realized that air pollution is a serious threat to quality of life and to a person’s health, especially among the most vulnerable, like our children and the elderly. According to the World Health Organization, millions of people die each year from illnesses related to air pollution. In Latin America, it is the number one environmental health risk, and causes more than 150,000 premature deaths per year. Cities like Mexico City, Monterrey (Mexico), Cochabamba (Bolivia), Santiago de Chile, Lima (Peru), Medellin (Colombia), San Salvador (El Salvador) and Bogota have the highest levels of air pollution in the region. When cities are allowed to expand without regulation, population skyrockets—and with it, so do the number of cars and trucks and factories. I worry about the future of my family in that scenario. I don’t want the air we breathe to negatively impact our health. My husband, who is not from Bogota, moved there to be with me. One year later, he was diagnosed with asthma. When my daughter was just two months old, she had a respiratory infection that put her in intensive care for several days. The cause of both their illnesses: the city’s poor air quality. Stopping the contamination The majority of the world’s population lives in cities. And while we can’t expect our cities to be pristine, natural ecosystems, they should provide people with the minimal conditions they need to lead dignified, healthy lives. That’s why AIDA works to improve air quality in Latin America, advocating for the protection of our children and other populations highly vulnerable to atmospheric contamination. We are raising awareness among policy makers about the importance of regulating short-lived climate pollutants (SLCPs), which stay in the atmosphere for a relatively short period of time. Unlike carbon dioxide, which can stay in the atmosphere for centuries, SLCPs remain in the air from a few days to a few decades. SLCPs include soot (also known as black carbon) and methane gas. These contaminants are major contributors to climate change, degrade air quality and have serious impacts on food security and human health. Effectively reducing them could significantly improve air quality and advance the fight against climate change in the short-term. Through our experience in international law, we’re seeking ways to regulate these short-lived pollutants across Latin America. Because having clean air to breath is one of life’s basic needs. Clean air shouldn’t be a luxury.
